MACHINE FOR PRODUCING TRINKETS FROM WOOD, 8w.

Specification of Letters Patent.

Patented Apr. 25, 11916.

Application filed July 6, 1914. Serial No. 849,350.

To all whom it may concern Be it known that I, JOI-IANN Sor-rowANEK, acitizen of the Empire of Austria-Hungary, and a resident ofAlbrechtsdorf, Bohemia, Austi-ia-l-lungary, have invented certain newand useful Improvements in Machines for Producing Trinkcts from Wood,&c., of which the following is a specification.

This invention has reference to improvements in machines for producingtrinkets and small ornamental fancy articles such as pearls, beads,buttons and the like made of wood, celluloid, ivory, horn, artificialhorn and different compositions of cellulose and similar materials. Suchsmall fancy articles are used for ornaments and trimmings for gowns,hand bags, necklaces, ornamental strings and bracelets. These articleswere usually made by means of a steel tool which acted on the rotatingmaterial, usually a rod. This steel tool shaped the article and anotherone cut it off from the rod of material. This device was defectivebecause the shaping steel tool became dull too easily and had to bereplaced very frequently. The shaping steel tool when becoming dull didnot produce clean articles and finishing had to be done involving lossof time and wages.

It is the purpose of the present invention to overcome the describeddefects. This has been primarily attained by employing one or morerotatable emery-disks or similar devices of a desired cross-sectionwhich disks are laterally advanced toward the rotating rod of material.By means of such rotatable abrasive disk a small article is produced ina single operation and directly polished and finished. This is one ofthe essential features of the present invention.

In order to render the invention entirely clear reference is had to theaccompanying drawing in which:

Figure 1 represents in longitudinal section a machine for producingtrinkets and the like embodying in desirable form the presentimprovements. Fig. 2 is a diagrammatical plan of the machine. Fig. 3illustrates the machine in a similar longitudinal section to Fig. 1.Fig. 4 is a similar diagrammatical plan view to Fig. 2. Fig. 5 is a viewsimilar to Figs. 1 and 3.

Similar characters of reference denote like parts in all the figures.

The material A forming the work piece is fed through the rotatable chuckB and usually consists of a rod which is mounted in the chuck B so thatit may be brought forward according to any approved manner and clampedtightly after it has been sufficiently advanced and accordingly rotateswith the chuck B.

F or the production of the single small fancy articles, for instance apearl, bead or button, the rotating work piece is, according to thepresent invention, acted on by a rotating emery-disk or similar diskhaving an abrasive effect. The disk D is mounted upon a sleigh support Eand may be shifted lengthwise upon said support. It is adjusted so thatthe vertical center point F of the disk D passes through the axis ofrotation of the material, see Figs. 1 and 2.

As shown in Fig. 5 the work piece A is held by the head stock I-I. Poweris applied by means of the pulley T and belt J.

The shaping and cutting off of the single fancy articles from the rod Aaccordingly is effected by the abrasive action of the disk D. Thedescribed arrangement permits of advancing the disk D sufiicientlytoward the rod to gradually shape the article and to cut same off. Thegreat speed of rotation of the shaping tool, that is the disk D,increased by the speed of the rotating work piece or rod renders itpossible that an article may be finished more quickly than with a steeltool, and second, the ground surface of the small fancy article attainsa high finish and does not'require any further work.

As waste material merely dust results which may be removed at once byapproved suction methods directly from the place where it is produced,while in former manufacture relatively large shavings were formed by theshaping steel tool. These shavings often were the cause of disturbanceswhen accidentally clamped in certain machine parts.

By the use of the described tools an in terruption of the work onaccount of required changes of steel tools is not necessary. On thecontrary, the work may be continued without interruption whereby alarger production per unit of time is obtained.

For the purpose of preventing a profile of the emery-disk or similarabrasive tool which is too sharp, the vertical center point F of thedisk D may be somewhat below the axis of rotation of the material 0.rod.

The small fancy article is then shaped as described and in order to cutoff the article the support E may be provided with a steel tool G. Thistool moves with the support E and is so arranged that it cuts off thearticle immediately after the same has been shaped and finished by theabrasive tool, as shown in Figs. 3 and 4.

I claim as my invention:

1. A machine for producing finished pearls, beads, buttons and similartrinkets of wood, celluloid, horn, ivory and artificial compositions ina single operation, comprising a rotatable chuck adapted to hold thework piece, a rotatable abrasive shaping tool having an abrasive workingsurface adapted to finish one-half of a fancy article and one-half ofthe next one, and means for advancing said tool toward the Workingpiece.

2. A machine for producing finished pearls, beads, buttons, and similartrinkets of wood, celluloid, horn, ivory and artificial comp'ositions ina single operation, comprising a rotatable chuck for holding the workpiece, a rotatable abrasive shaping disk having a. circumferencefinishing onehalf of an article and one-half of the next one so that onearticle is produced by each single operation, and means for advancingthe disk toward the work piece, so arranged that the vertical centerpoint of the disk passes approximately through the axis of rotation ofthe work piece.

Signed at Leipzig, Germany, this 16th day of June, 1914.
